One of the biggest stories in Formula 1 has been the struggles of the McLaren-Honda team to be competitive. When the Japanese automaker rejoined the F1 circus one year into the 1.6-liter V6 hybrid formula, it was expected to rocket to the top of the timing sheets based on past performance and the fact that it had sat out a year in order to assess the situation before settling on a powertrain design. Unfortunately, the Honda powertrain proved to be seriously down on power, and suffered from a number of other troubles including an overheating battery pack. It was far from competitive.

Rectifying the problem was made more difficult by the FIA’s token system that limited development — and cost — by dividing the power unit into sections, then allowing certain number of tokens to cover these areas while limiting the total number of tokens that could be used during the season. If you got your sums right the first time, this restriction wasn’t a problem. Get them wrong, however, and you could find yourself unable to make significant gains during the season; a fate that befell both Honda and Renault, though not quite to the same extent.
